Certificate Revocation in Vehicular Networks

Abstract: Among civilian communication systems, vehicular net-works emerge as one of the most convincing and yetmost challenging instantiations of the mobile ad hocnetworking technology. Towards their deployment, se-curity is a critical factor and signiOcant challenge to bemet. In this paper, we are concerned with the problemof certiOcate revocation in vehicular networks, a prob-lem of central importance for any security architectureand particularly di±cult for vehicular networks. Wecontribute a set of protocols for e±cient and eAEectiverevocation, to evict illegitimate or faulty network nodes.Furthermore, we propose a protocol that enables nodesto collectively shield themselves against faulty of mali-cious operation of other nodes and contribute to theireviction. We show, by means of simulations, that oursolution is feasible and achieves a su±cient level of ro-bustness in spite of the unique challenges of the vehic-ular networking environment.

Enhancing Crowd Collaborations for Software Defined Vehicular Networks

Abstract: Vehicular networking is promising to improve traffic efficiency and driving safety, as well as travel experience. However, the traditional network employs a highly coupled design, which is quite limited in its ability to satisfy various challenging vehicular demands. Recently, new studies focus on how to design software defined vehicular networks smartly to meet various vehicular demands. In this article, we investigate a new smart identifier networking (SINET) paradigm and propose a SINET customized solution enabling crowd collaborations for software defined vehicular networks (SINET-V). In particular, through crowd sensing, network function slices are well organized with a group of function-similar components. Different function slices are further driven to serve various applications by using crowd collaborations. We clearly illustrate how SINET-V works and also analyze its potential advantages in several special vehicular instances. Experimental results show that SINET-V has great potential to promote powerful vehicular networks.

Cognitive vehicular communication for 5G

Abstract: Device-to-device (D2D) is increasingly becoming a prominent technology within the 5G story, portrayed as a means of offloading traffic from the core network. The ever increasing demand for vehicular traffic consumption is providing the impetus for a new architectural design that can harness the benefits of D2D for vehicular users, taking a step toward offloading vehicular traffic from the core network. We propose the notion of extending D2D for vehicular scenarios with the potential to coordinate vehicular traffic using the LTE band. Furthermore, we then extend this approach by investigating cognitive radio in synergy with a geo-location database, to exploit white spaces as a means of further offloading vehicular users. Our simulation results have shown that our approach can outperform the legacy IEEE 802.11p in terms of delay.

Secure and Privacy-Aware Cloud-Assisted Video Reporting Service in 5G-Enabled Vehicular Networks

Abstract: Vehicular networks are one of the main technologies that will be leveraged by the arrival of future fifth-generation (5G) mobile cellular networks. While scalability and latency are the major drawbacks of IEEE 802.11p and fourth-generation (4G) Long-Term Evolution (LTE)-enabled vehicular communications, respectively, the 5G technology is a promising solution to empower the real-time services offered by vehicular networks. However, the security and privacy of such services in 5G-enabled vehicular networks need to be addressed first. In this paper, we propose a novel system model for a 5G-enabled vehicular network that facilitates a reliable, secure, and privacy-aware real-time video reporting service. This service is designed for participating vehicles to instantly report the videos of traffic accidents to guarantee a timely response from official vehicles and/or ambulances toward accidents. While it provides strong security and privacy guarantees for the participating vehicle's identity and the video contents, the proposed service ensures traceability of misbehaving participants through a cooperation scheme among different authorities. We show the feasibility and the fulfillment of the proposed reporting service in 5G-enabled vehicular networks in terms of security, privacy, and efficiency.

V-Cloud: vehicular cyber-physical systems and cloud computing

Abstract: The widespread use of smart phone devices and their ubiquity has brought up new application domains. One such interesting domain is vehicular networks. Furthermore, cloud computing is a next-generation information and communication technology that is gaining popularity due to its pay-as-you-go service model. In this paper, we propose our novel V-Cloud architecture which includes vehicular cyber-physical system (VCPS), vehicle-to-vehicle network (V2V) and vehicle-to-infrastructure network (V2I) layers. Each of these layers is explained in further details. We discuss research challenges in V-Cloud domain and introduce new services to show wide potential of such intelligent transportation system to meet safety and comfort requirements for driver.
